本篇文章為大家展示了CentOS sensors軟件如何監控主板CPU數據,內容簡明扼要并且容易理解,絕對能使你眼前一亮,通過這篇文章的詳細介紹希望你能有所收獲。
在Linux下有個叫CentOS sensors的軟件可以幫助我們來監控主板,CPU的工作電壓,風扇轉速、溫度等數據。這些數據我們通常在主板的 BIOS也可以看到。當我們可以在機器運行的時候通過CentOS sensors隨時來監測著CPU的溫度變化,可以預防呵保護因為CPU過熱而會燒掉。
1. 安裝CentOS sensors現在基本上每個Linux都已經有CentOS sensors包了,我們主要安裝了就可以了。或者我們也可以通過源文件來自己編譯。1)在FC,RH, CENTOS下,用rpm:[root@securitycn ~]# rpm -ivh lm_sensors-2.10.0-3.1.i386.rpm3)編譯源文件安裝我們可以通過:這里下載源文件這里我們要注意的問題是要先安裝libsysfs庫,是Sysfsutils,Sysfsutils-devel軟件
tar xzvf lm-sensors-xxx.tar.gz make user make user_install testing
下面我們就用一些簡單的命令來利用CentOS sensors來得到CPU的數據。我們要用root的身份來:sensors-detect,然后它會自動搜索主板上的chipset和相應的driver,我們全部答YES就可以了[root@securitycn ~]# sensors-detect
# sensors-detect revision 1.413 (2006/01/19 20:28:00) This program will help you determine which I2C/SMBus modules you need to load to use lm_sensors most effectively. You need to have i2c and lm_sensors installed before running this program. Also, you need to be `root', or at least have access to the /dev/i2c-* files, for most things. If you have patched your kernel and have some drivers built in, you can safely answer NO if asked to load some modules. In this case, things may seem a bit confusing, but they will still work. It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. We can start with probing for (PCI) I2C or SMBus adapters. You do not need any special privileges for this. Do you want to probe now? (YES/no):
全部默認YES即可。然后我們啟動CentOS sensors:
/etc/init.d/lm_sensors start Starting lm_sensors: [ OK ]
我們可以通過lsmod來確定我們需要的driver已經加載了沒有
lsmod | grep i2c i2c_isa 9153 2 w83627hf,w83781d i2c_i801 11341 0 i2c_dev 12613 0 i2c_ec 9025 1 sbs i2c_core 23745 6 w83627hf,w83781d,i2c_isa,i2c_i801,i2c_dev,i2c_ec
然后我們用CentOS sensors的命令就可以了:
[root@securitycn ~]# sensors w83627hf-isa-0290 Adapter: ISA adapter VCore 1: +3.33 V (min = +0.00 V, max = +0.00 V) ALARM VCore 2: +3.36 V (min = +0.00 V, max = +0.00 V) ALARM +3.3V: +0.93 V (min = +3.14 V, max = +3.46 V) ALARM +5V: +5.11 V (min = +4.73 V, max = +5.24 V) +12V: +4.56 V (min = +10.82 V, max = +13.19 V) ALARM -12V: -7.10 V (min = -13.18 V, max = -10.88 V) ALARM -5V: -1.93 V (min = -5.25 V, max = -4.75 V) ALARM V5SB: +5.51 V (min = +4.73 V, max = +5.24 V) ALARM VBat: +0.02 V (min = +2.40 V, max = +3.60 V) ALARM fan1: 0 RPM (min = 2732 RPM, div = 2) ALARM fan2: 0 RPM (min = 0 RPM, div = 2) fan3: 0 RPM (min = 0 RPM, div = 2) temp1: +38癈 (high = +50癈, hyst = +45癈) sensor = thermistor temp2: +33.5癈 (high = +80癈, hyst = +75癈) sensor = thermistor temp3: +33.5癈 (high = +80癈, hyst = +75癈) sensor = thermistor vid: +0.000 V (VRM Version 10.0) alarms: beep_enable: Sound alarm enabled
這里我們可以看到溫度還沒有相對應CPU,我們主要稍微修改一下/etc/sensors.conf就可以了,不過其實都不用我們自己去動手,一般我們都可以從主板生產商那里下載到配置文件。通過CentOS sensors我們就可以得到主板溫度,CPU電壓,風扇轉速這些信息。我們可以根據這些數據來監察系統的運行情況來預防系統的問題。
接下來讓它和MRTG整合在一起吧
[root@securitycn ~]# cd /usr/local/mrtg/bin [root@securitycn ~]# vi temp.sh #內容如下 #!/bin/bash cputemp=`/usr/bin/sensors | grep temp1 |awk '{print $2}'|cut -c 2-4` #這句是說找出有temp1那一行,印出第二個列的2-4個字 systemp =`/usr/bin/sensors | grep temp2 |awk '{print $2}'|cut -c 2-5` 不用解釋了吧 echo $cputemp echo $systemp # the uptime uptime | sed 's:^.* up \(.*\), [0-9][0-9]* users.*$:\1:' # my name uname -n
[root@securitycn ~]# chmod +x temp.sh 改成可執行 [root@securitycn ~]# ./temp.sh 試試看有沒有問題 39 33.5 15:36:19 up 22:28, 1 user, load average: 0.04, 0.09, 0.04 securitycn
CentOS sensors再來寫下面的文件
[root@securitycn ~]# cd ../etc/ [root@securitycn ~]# vi temp.cfg
WorkDir: /data1/usr/apache/htdocs/mrtg/temp/ Target[index]: `/usr/local/mrtg/bin/temp.sh` MaxBytes[index]:80 Options[index]: gauge, nopercent, growright YLegend[index]: Temp (度) ShortLegend[index]: 度 LegendO[index]: 系統溫度; LegendI[index]: CPU溫度; Title[index]: 系統溫度表 PageTop[index]: <H1>主機溫度表</H1>
[root@securitycn ~]# /usr/local/mrtg/bin/mrtg /usr/local/mrtg/etc/temp.cfg執行3次就不報錯了然后加入到crontab里面*/5 * * * * /usr/local/mrtg/bin/mrtg /usr/local/mrtg/etc/temp.cfgPageTop[index]: <H1>主機溫度表
